Engine reseal, cooling system upgrade and A/C compressor upgrade.

I just completed another project on our 82 Avanti to stop all the oil leaks.  99K miles on the 305.  I replaced the rear mail seal, the oil pan gasket, the timing cover seal/gasket/ timing chain and the fuel pump/gasket.  All oil leaks have now stopped.  While doing this, I decided to install a high volume water pump and convert the radiator fan to electric.  I chose the Flexalite Black Magic Fan with Shroud #188 and variable speed controller #31165 with the thread-in water temp sensor.  The controller starts the fan up at 60% and ramps up to 100% as needed.  It turns on with the A/C compressor and you can add a manual off/on switch if you want.  This fit the stock radiator almost perfect!  The fan draws 18 amps at 100%, so I went ahead and replaced the stock 63 amp alternator with a 100 amp model.  Lastly, the old GM 6 cylinder steel A/C compressor was leaking at the front seal, so I replaced it with the newer aluminum 10 cylinder model.  Total parts cost was right at 1K and I found that Summit had the best prices.

Looks like it really opend up the front of the motor removing the standard fan. Nice job

Nice work! Let us know how the electric fan set-up works out.

I also would love to know how that works out with cooling the engine on a hot day.

The fan has worked like a champ.  No complaints on it at all.
